We remember getting our iPhone and thinking about how crazy this technology was. (Yes, we used Google Maps on a desktop, but on this little device, there was something special about it.) Apple now has its own maps.

After he was done wrapping up the software demo, Dr. Eric Schmidt came on stage.

Google and Apple weren't enemies yet. Schmidt was still on Apple's board at the time, and he even joked that there was so much overlap between Apple and Google, they "could just merge the companies and make them 'Apple Goo.'" After all, their "cultures are similar," said Schmidt. Hard to see anything like that happening again.

Guess who else was there? JERRY YANG!

Apple is still tight with Yahoo, but it now has Marissa Mayer as CEO.

After the guests left, Jobs talked specs.

Battery life was 5 hours then. It's 10 hours now.

He also boasted of Apple picking up 200+ patents making the iPhone.

Those have been somewhat helpful in its battles with Samsung. But overall, Apple's patents haven't done all that much.

Initially, the phone cost $499 at its cheapest.

Today you can get an iPhone for as little as $0 with a 2-year contract. But off contract, the newest iPhone is still $650.

Apple partnered with Cingular, renamed AT&T at this keynote, which was the largest carrier.

Now, it's on carriers all over the world. The biggest is China Mobile, which it just added.

Stan Sigman, Cingular's CEO was on stage, reading from cards, which was funny since everyone else memorized their speech.

Pretty sure this has never happened since.

At the time, there were 1 billion mobile phones in the world.

Apple

Today, there are over 6 billion.

Jobs knew the iPhone was big, so he ended his keynote by changing the name of the company from Apple Computer to Apple Inc. to reflect its shift to mobile.

And he was right! Apple is now the iPhone company with the bulk of its revenue coming from the iPhone.
